Thin LiveDashboard page over Rheo inspect APIs (ADR 027).

Read-only: group health (lag, inflight, dead letters / DLQ). Does not settle leases. A dead letter is a delivery parked for the group after reject or exhausted nacks — see the ops guide.

Enable with:

{:phoenix_live_dashboard, "~> 0.8"}

and register in your router:

live_dashboard "/dashboard",
  additional_pages: [rheo: Rheo.LiveDashboard.Page]

Configure the Rheo instance via application env:

config :rheo, Rheo.LiveDashboard, rheo: MyRheo

Try without a host Phoenix app: iex examples/live_dashboard_ops.exs or notebooks/live_dashboard.livemd (control panel + this page). See the ops guide.
